Abstract ZHANG Xiao-yu1, CHEN Yu-ying2, SU Zhan-sheng1,ZHOU Hui-qin1, MA Yu-ping3(1.Ningxia Meteorological Institute, 2.Ningxia Meteorological Observatory,3Ningxia Meteorological office,Yinchuan750002,China)Abstract:The frost occurred is lies on many factors, such as condition of weather, landform, soil texture,bacterial population and vegetation itself etc. To monitor the frost by using remote sensing, we have tosolve many problems, for example, the precision of temperature retrieval and distribution of vegetation byusing NOAA data. In addition, we have to consider to both the aerosol and humidity effect on the temper-ature retrieval. Due to above mentioned reasons, monitoring the frost by remote sensing is rather compli-cated and difficult.Based on the analysis of the characteristic and the law of the frost, using the data of NOAA andweather station during 1991 to 2000,as well as using the data of the frost damage, there are three methodswere introduced to monitor the frost in Ningxia in this paper. The first is difference vegetation index(DVI) which monitoring the frost by means of the difference of vegetation index between fore-frost and af-ter-frost. The second is temperature reference (TR) which monitoring the frost by compare to the differ-ence between the temperature retrieval and frost index of crops. The third is the area of cold valley(ACV) which obtained ACV by integral the temperature below the frost index. We have examined themonitoring precision of those methods, the results show that each is available to monitor the different typeof frost in Ningxia.Key words:Vegetation index, AVHRR, Minimum temperature, Frost, Remote sensing
